My problem is very high DPC latency which is making all my games stutter/lag. I have had this problem since building my rig yet I have not been able to fix it. So far I have:
reinstalled windows 7
changed PCI-e lanes for my GPU
disabled hardware in device manager
I have used latencymon which shows that for the most part its directx causing the issue however where do I go from there?
Also if I disable my GPU in device manager the latency completely goes. Again like with the directx I cannot find a way around this as clearly I cannot operate with my GPU disabled.
AMD Phenom X4 955
Zotac GTX 670
Corsair Force 3 120GB
Asus M4A88DT-V USB3/EVO
Any assistance will be greatly appreciated. Thanks.
